GUSTAVE MADDEN, OF CHICAGO, ILLINOIS, ASSIGNOR- TO THE ADAMS & WESTLAKECOMPANY, OF SAME PLACE.

ROTATABLE SIGNAL-LANTERN.

SPECIFICATION forming part of Letters Patent No. 387.981, dated August14, 1888.

Application filed February 18, 1888. Serial No. 264,496. (No modciju Toall whom it may concern.-

Be it known that I, GUSTAVE MADDEN, of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Rotatable Signal-Lanterns, of which the following is a fullspecification.

My invention is intended to facilitate the adjustment of the lantern inits support, so as to display one or another of the different col- 1oored lenses, as may be desired, and is especially applicable tosignal-lanterns which are carried on the rear of trains, and is shown inconnection with such a lantern, though it may be used in othersituations.

My invention consists in the combinations hereinafter described andclaimed.

In the accompanying drawings, Figure 1 is a side view of a lanternembodying my invention, the lower part being shown in section. Fig. 2 isa view from above of the lower part of the lantern. Figs. 3 and 4 areviews corresponding to Figs. 1 and 2, respectively, show ing amodification ofthe locking devices shown in Figs. 1 and 2.

A, Fig. l, is a bracket which is fitted to engage a socket fastened tothe side of the car in the usual and well-known manner. The outer end ofthe bracket A carries a ring, B, which surrounds the lantern just aboveits base and forms a support therefor.

In the base of the lantern a cross-handle,D, is firmly secured. Near oneend of the cross handle a casing, E, rises, which incloses and forms aguide for the vcrticallyslidiug catch O. The catch 0 fits in recesses1'), formed at intervals around the ring B, and is held in engagementtherewith by the spiral spring F, within the casing E, one end of whichabuts against the casing E and the other against a 4,0 shoulder on thecatch 0. The projection 0 serves to release the catch 0 when pressure isapplied thereon.

The construction shown in Figs. 3 and 4.

diifers from that just described in that the catch 0 moves downwardinstead of upward in releasing, the projection 0 being above the handleD instead of below, and the recesses I) being in the lower instead ofthe upper edge of the ring B.

In both cases the operation is the same, the projection c or 0 beingpressed by the thumb or finger nearer the cross-handle D, so as torelease the catch whenever the handle is grasped in order to turn thelantern. No in dependent motion of the hand or fingers being 5 5 neededto release the catch 0, it is released and the lantern is turned withthe least possible trouble. Two forms of recess b are shown-namely,holes and notches. No claim is made for these, because either form maybe used with either arrangement of the catch G- that is, the catch 0 ofFig. 1 might be made to fit a series of holes in the ring 13, as in Fig.

3, and vice versa.

I claim- 1. In a rotatable signal-lantern, the combination of a ringsupporting the lantern and having a series of recesses in its edge, acrosshandle rigidly secured in the bottom of the lantern, averticallysliding catch, and a spiral 7o spring surrounding the catchand holding it in engagement with said recesses in the supporting-ring,substantially as set forth.

2. In a signal-lantern, the combination ofa ring supporting the lanternand having a series 5 of recesses in its upper edge, a cross-handlerigidly secured in the bottom of the lantern, averticallysliding catchhaving a downwardly projecting thumb-piece, and a spring tending to keepsaid sliding catch in engagement with said recesses in thesupporting-ring, substantially as described.

GUSTAVE MADDEN.
